Although geologists can use seismic data from large earthquakes to see features deep in the earth, the shallow subsurface geology of the park has remained a mystery, because mapping it out would require capturing everyday miniature ground movement and seismic energy on a much smaller scale.
«Other major faults of the San Francisco Bay Areas, including Rodgers Creek, Northern Calaveras and Concord - Green Valley, also expect large earthquakes, and should expect significant afterslip, especially in locations where interseismic creep rates are high, and where faults cross deep sedimentary basins,» Lienkaemper added.
Since his early research on deep earthquakes, Vedran Lekic has repeatedly developed new ways of analyzing and modeling seismic data, leading to improved understanding of Earth's large - scale inner strucutre.
A Ph.D. student from the University of Texas used an innovative method for analyzing deep seismic waves from large earthquakes to reveal a cylindrical column of hotter - than - normal magma rising from deep below Mexico and surfacing right below the Yellowstone supervolcano, according to a paper published in Nature Geoscience.
Because the faults that break during the earthquake are so deep, the seismic wave energy they radiate spreads over a much larger area than in a shallow quake.
